///\brief Resets the id of the passed-in object.

///\exception H5::Exception's subclasses, thrown by p_close
///\par Description:
/// This function is used to reset an IdComponent object
/// before using it again for another HDF5 object. If
/// the member \a id is the valid id of an HDF5 object, which
/// this IdComponent object represents, the associate close
/// function will be called to properly close the HDF5 object.
//
// Note: Some older compilers don't support template member functions;
// so at this time, resetIdComponent is not a member function so
// it can be template to work around that problem.
